Points into Ravens are pretty much wasted. If you're putting three in because you want to be able to summon three of them, +skills from gear will do that easily. You can't use Dire Wolves at the same time as Grizzly anyway. They do provide a synergy to the health of Grizzly, but that's probably not too important.

Instead of all that stuff, put a bunch of points into Maul. That's the thing you'll actually be using to kill stuff, so put points into it.
